Frederick Albert Urquhart (December 13, 1911 – November 3, 2002) was a
Canadian zoologist and professor of zoology who studied the migration of
monarch butterflies, ''Danaus plexippus'' L. Together with his wife,
Norah Roden Urquhart , he identified their migration routes, discovered that the migration spans multiple generations of butterflies, and found their wintering place in Mexico—considered "one of the greatest natural history discoveries" of the 20th-century.
